F. Gosling and J. M. Kent, and is managed by the Avon Wildlife Trust. Ecology The site of the fort and warren is now grassy slopes which attract a wide range of wild flowers and butterflies. The differing soil types provide suitable habitats for both acid- and lime-loving plants. Kidney vetch (Anthyllis vulneraria), harebell (Campanula rotundifolia) and woolly thistle (Cirsium eriophorum) thrive on the dry stony soils. Heath bedstraw (Galium saxatile) and wood sage (Teucrium scorodonia) are found in more acidic areas. The higher areas support bell heather (Erica cinerea), western gorse (Ulex gallii) and common heather (Calluna vulgaris). Trees and shrubs include the wayfaring tree (Viburnum lantana), guelder rose (Viburnum opulus), whitebeam (Sorbus aria), privet (Ligustrum vulgare) and dogwood (Cornus sanguinea). Scarce plants found at the warren include knotted pearlwort (Sagina nodosa), and slender bedstraw (Galium pumilum). Butterflies recorded here include the small blue (Cupido minimus), marbled white (Melanargia galathea), dingy skipper (Erynnis tages), grizzled skipper (Pyrgus malvae), small pearl-bordered fritillary (Boloria selene), and wall brown (Lasiommata megera).
